Die Erfindung bezieht sich auf eine Einrichtung zur Herstellung einer für Wärmeisolierungszwecke geeigneten Bahn oder Matte, bei der eine Anzahl von Glasfäden, aus einer Düse ausgezogen und zu einem Strang zusammengefaßt werden, der dann, bevor er zur Bildung einer Bahn oder Matte an einem Sammelförderer weitergeleitet wird, durch eine Kräuselungsvorrichtung geschickt wird.The invention relates to a device for making one suitable for thermal insulation purposes Web or mat in which a number of glass threads are drawn out of a nozzle and into one Strand are summarized, which is then before it to form a web or mat on a collecting conveyor is passed through a crimper.
Es ist eine Einrichtung oben genannter Art bekannt, bei der die Kräuselung des Strangs dadurch erfolgt, daß er mit hoher Geschwindigkeit auf eine Prallfläche geschleudert wird, an der er eine starke Richtungsänderung erfährt und durch die unterschiedliche Beanspruchung der Einzelfasern beim Aufprallen und Abknicken eine stark faserige und gekräuselte Gestalt annimmt. Anschließend wird der Strang durch Schwenken der Prallfläche mit Unterstützung eines Luftstromes zur Bildung einer Matte zu einer Fördervorrichtung geleitet und mit einem Bindemittel besprüht. Bei dieser bekannten Einrichtung wird der Strang kontinuierlich auf einem Förderband der Fördereinrichtung abgelegt.A device of the type mentioned above is known in which the crimping of the strand thereby takes place that he is thrown at high speed on a baffle on which he has a strong Changes in direction and due to the different stresses on the individual fibers during impact and buckling takes on a highly fibrous and curled shape. Then the strand is through Pivoting the baffle with the support of an air flow to form a mat to a conveyor device directed and sprayed with a binder. In this known device, the Strand is continuously deposited on a conveyor belt of the conveying device.
Aufgabe der Erfindung ist es, eine Einrichtung zu schaffen, die es ermöglicht, in stärkerem Maße aufgelockerte, poröse Matten herzustellen, die noch besser für Isolationszwecke geeignet sind.The object of the invention is to create a device that enables to a greater extent loosened, to produce porous mats that are even better suited for insulation purposes.
Erfindungsgemäß wird der Strang aus Einzelfäden, insbesondere Glasfäden, um ihm eine faserige oder gekräuselte Gestalt zu geben, mit Hilfe eines Preßluftstrahls unter starker Richtungsänderung über eine Messerschneide gezogen und anschließend in eine Sammelkammer umgelenkt, die an ihrem Auslaßende eine düsenförmige Verengung besitzt. Der Austrittsquerschnitt der Verengung ist so bemessen, daß sich der gefaserte Strang darin aufstaut. Der sich aufstauende gekräuselte Strang behindert dann in zunehmendem Maße den Luftstrom durch die Verengung, bis sich hinter dem Strang ein Luftdruck aufgebaut hat, der genügt, um den aufgestauten gekräuselten Teil des Stranges durch die Austrittsöffnung hindurch- und zu dem Sammelförderer zu stoßen. Dabei reißt der ausgestoßene Teil vom kontinuierlichen Hauptstrang ab. Dieser Vorgang wiederholt sich periodisch, auch wenn mit einem kontinuierlichen Luftstrom gearbeitet wird.According to the invention, the strand of individual threads, in particular glass threads, to give it a fibrous or To give curled shape, with the help of a compressed air jet with a strong change of direction over a Knife edge drawn and then deflected into a collecting chamber at its outlet end has a nozzle-shaped constriction. The exit cross-section of the constriction is dimensioned so that the fibrous strand accumulates in it. The piling up crimped strand then hinders increasing Measure the airflow through the constriction until air pressure has built up behind the strand, which is sufficient to pass the pent-up, crimped part of the strand through the outlet opening and to close it to bump into the collecting conveyor. In the process, the ejected part tears from the continuous main strand away. This process is repeated periodically, even when working with a continuous flow of air will.
Die Matten, die mit Hilfe der erfindungsgemäßen Vorrichtung hergestellt werden, bestehen also aus lauter abgetrennten gekräuselten Strangabschnitten. Diese Einrichtung ermöglicht nicht nur stark aufgelockerte und damit für Wärmeisolierungszwecke noch geeignetere Matten herzustellen, sondern den Matten auch ein gleichmäßigeres Gefüge zu geben, da sich einzelne Einrichtung zum Herstellen einer für Wärmeisolierungszwecke geeigneten Bahn oder MatteThe mats that are produced with the aid of the device according to the invention therefore consist of noisy severed curled sections of strand. This facility allows not only very relaxed and thus to produce mats that are even more suitable for thermal insulation purposes, but also the mats to give a more uniform structure, as there is a single facility for making one for thermal insulation purposes suitable sheet or mat

F i g. 3 zeigt die Kräuselungs- und Abtrennvorrichtung gemäß F i g. 2 in einer Seitenansicht.F i g. 3 shows the crimping and severing device according to FIG. 2 in a side view.
Bei einer erfindungsgemäßen Einrichtung werden kontinuierlich aus dem Ofen 2 austretende Einzelfäden 1 aus Glas mit Hilfe eines Aufgabetrichters gesammelt und einer V-förmigen Nut 4 an der Außenfläche einer Trommel 5 zugeführt, von der sie mit Hilfe einer mit Luft betriebenen Zugvorrichtung 6 unter Bildung eines Stranges 7 abgezogen werden, der dann an ein Rohr 8 weitergegeben wird.In a device according to the invention, individual threads emerging continuously from the furnace 2 are produced 1 collected from glass using a feed hopper and a V-shaped groove 4 on the outer surface fed to a drum 5, from which it is pulled by means of an air-operated pulling device 6 be withdrawn to form a strand 7, which is then passed on to a tube 8.
An das Austrittsende dieses Rohres schließt sich eine weitere mit Luft arbeitende Zugvorrichtung 9 an, die den Strang 7 aus dem Rohr 8 heraus- und unter scharfer Richtungsänderung über eine Messerschneide 10 hinwegzieht, die nahe dem Einlaß der Vorrichtung 9 angeordnet ist. Dabei werden die einzelnen Fäden des Stranges unterschiedlich beansprucht und wahllos gekräuselt. Der gekräuselte Strang wird dann vor dem Austrittsrohr 12 in eine Kammer mit einer düsenförmigen, durch einen trichterförmigen Abschnitt 11 gebildeten Verengung 13 geleitet, vor der er sich kurzzeitig ansammelt und den Luftstrom durch die Verengung 13 in das anschließende Austrittsrohr 12 behindert. Wenn sich hinter dem gekräuselten Strang ein genügender Luftdruck aufgebaut hat, wird der in dem trichterförmigen Abschnitt 11 enthaltene Teil des Stranges aus diesem herausgepreßt und dabei von dem durchlaufenden Strang 7 abgetrennt. Die für den Betrieb der Zugvorrichtungen 6 und 9 benötigte Druckluft wird von einem Verdichter 14 geliefert, der durch einen Elektromotor 15 oder einen anderen geeigneten Motor angetrieben wird.At the outlet end of this tube, another pulling device 9 working with air is attached, which the strand 7 out of the tube 8 and with a sharp change of direction over a knife edge 10, which is arranged near the inlet of the device 9. The individual The threads of the strand are stressed differently and crimped indiscriminately. The curled strand is then in front of the outlet pipe 12 in a chamber with a nozzle-shaped, through a funnel-shaped section 11 formed constriction 13 passed, in front of which it accumulates briefly and the air flow through the constriction 13 obstructs the adjoining outlet pipe 12. If behind the ruffled Strand has built up a sufficient air pressure, that contained in the funnel-shaped section 11 is Part of the strand pressed out of this and thereby separated from the continuous strand 7. the Compressed air required for the operation of the pulling devices 6 and 9 is supplied by a compressor 14, which is driven by an electric motor 15 or some other suitable motor.
Die abgetrennten Strangabschnitte werden von dem Austrittsrohr 12 in der bei la angedeuteten Weise an einen Sammelförderer abgegeben, der von zwei im Abstand übereinander angeordneten FörderbändernThe separated strand sections are delivered from the outlet pipe 12 in the manner indicated at la to a collecting conveyor, which is provided by two conveyor belts arranged one above the other at a distance
16 und 17 gebildet wird, die beispielsweise aus einem weitmaschigen Werkstoff bestehen. Bevor die Strangabschnitte zwischen die Förderbänder gelangen, werden sie mittels einer Düse 18 oder anderen Sprüheinrichtungen mit einem Bindemittel bespritzt. Um das Bindemittel zu trocknen oder zu härten, wird heiße Luft über Verteilerköpfe 19 zugeführt, die an Abzweigungen 20 einer Heißluftzuleitung 21 angeschlossen sind.16 and 17 is formed, which for example consist of a wide-meshed material. Before the strand sections get between the conveyor belts, they are by means of a nozzle 18 or other spraying devices sprayed with a binder. To dry or harden the binder, it is hot Air is supplied via distributor heads 19, which are connected to branches 20 of a hot air supply line 21 are.
Das Ende des Austrittsrohres 12 kann, wie es bei 12 a angedeutet ist, mit einem seitlich hin- und herschwenkbaren Abschnitt versehen werden, um die Strangabschnitte la auf dem Förderband 17 besser zu verteilen. Gegebenenfalls können, je nach Breite der Förderbänder, auch zwei oder mehr Vorrichtungen 9 zum Kräuseln und Abtrennen der Stranges nebeneinander auf der Einlaufseite eines einzigen Sammelförderers angeordnet werden.The end of the outlet pipe 12 can, as indicated at 12 a, be provided with a laterally pivotable section in order to better distribute the strand sections la on the conveyor belt 17. If necessary, depending on the width of the conveyor belts, two or more devices 9 for crimping and severing the strand can be arranged next to one another on the inlet side of a single collecting conveyor.
Der Abstand zwischen den Förderbändern 16 undThe distance between the conveyor belts 16 and
17 ist vorzugsweise einstellbar, damit man die Dicke der hergestellten Bahn oder Matte 22 beeinflussen kann. Die Dichte der Bahn oder Matte läßt sich durch entsprechendes Steuern der Bewegungsgeschwindigkeit der Förderbänder 16 und 17 beeinflussen. Es ist ohne Schwierigkeiten möglich, jede gewünschte Dichte zwischen etwa 0,008 und etwa 0,16 kg/1 zu erzielen. Art und Menge des verwendeten Bindemittels lassen sich so wählen, daß man Matten in jeder Abstufung zwischen biegefest und biegsam herstellen kann.17 is preferably adjustable in order to influence the thickness of the web or mat 22 produced can. The density of the web or mat can be adjusted by controlling the speed of movement accordingly affect the conveyor belts 16 and 17. It is possible to make any desired one without difficulty Achieve density between about 0.008 and about 0.16 kg / l. Type and amount of binder used can be selected in such a way that mats can be produced in any gradation between rigid and flexible can.
